Heat 1 tbsp oil in a skillet over high heat, and quickly brown the pork chops on both sides. Transfer chops to platter, and keep warm.
Reduce skillet heat to medium. Add 1 tbsp oil and heat until shimmering. Add the onion and cook until tender. Add garlic and saute until fragrant, about 1 minutes. Mix in the sugar, chili powder, fennel, oregano and basil. Stir in the tomatoes and Worcestershire sauce, and bring to a boil.
Return the pork chops to the skillet. Cover, reduce heat to low, and cook 10 minutes. Remove cover, and continue cooking another 15 minutes, or to desired doneness.
